To evaluate the feasibility of this customized EMI-II intervention, the investigators will examine the proportion of study participants completing the two-week intervention period, Week 2 in the Immediate Intervention arm and week 4 in the Waitlist arm.
| Group | Value | 95% CI |
|---|---|---|
| Immediate Intervention | 25 | |
| Waitlist | 31 |
To examine the acceptability of the EMI-II intervention, participants will rate the acceptability of the intervention on a Likert scale ranging from 1 (low acceptability) to 5 (high acceptability) on the two weekly surveys completed during the intervention period.
| Group | Value | 95% CI |
|---|---|---|
| Immediate Intervention | 3.85 | ± 0.84 |
| Waitlist | 3.55 | ± 0.97 |
Self-reported cigarette smoking will be assessed five times per day (morning, late morning, early afternoon, late afternoon, evening) during the intervention period. Participants will respond via text messaging to the question, "Since the last prompt, how many cigarettes have you smoked?"
| Group | Value | 95% CI |
|---|---|---|
| Immediate Intervention | 30.3 | ± 7.1 |
| Waitlist | 30.1 | ± 5.0 |
This study will develop an ecological momentary implementation intentions intervention (EMI-II) for cigarette smoking, which will link critical situations where smoking is likely to occur with alternative responses to support avoidance of cigarette use. Using ecological momentary assessment (EMA) for data collection, this project will evaluate the feasibility, acceptability, and initial effectiveness of a micro-randomized trial (MRT) of EMI-II targeting cigarette smoking reduction in a sample of adults who smoke a minimum of 15 cigarettes per day (n=100).
